What is the difference between markup and margin?

Markup is the percentage added to your cost to arrive at the selling price, calculated as a percentage of cost. Margin (also called gross margin) is the percentage of the selling price that represents profit, calculated as a percentage of the selling price. For example, a product costing $80 sold at $100 has a 25% markup but only a 20% margin.

How do you convert markup to margin?

To convert markup to margin: Margin = Markup / (1 + Markup). For example, a 25% markup equals 0.25 / 1.25 = 0.20 or 20% margin. To convert margin to markup: Markup = Margin / (1 − Margin). A 20% margin equals 0.20 / 0.80 = 0.25 or 25% markup.

Which is better for pricing: markup or margin?

Margin is generally better for financial analysis because profit is always expressed as a percentage of revenue, making it easier to compare across products and periods. Markup is more intuitive for cost-plus pricing and is commonly used in retail and manufacturing. Both are important — margin for analysis and markup for pricing decisions.

Markup vs. Margin: What's the Difference?

Author: Finatune

If you run a business, you've probably heard the terms markup and margin used interchangeably. But they are not the same thing — and confusing them can cost you thousands of dollars in lost profit.

Markup and margin are two different ways of looking at profitability. Markup measures how much you increase the cost to get the selling price. Margin measures how much profit you keep from each sale. Understanding the difference is essential for accurate pricing, financial analysis, and business planning.

What Is Markup?

Markup is the percentage added to your cost to arrive at the selling price. It's calculated as a percentage of the cost, not the selling price.

Markup % = (Selling Price − Cost) ÷ Cost × 100

For example, if a product costs $80 and you sell it for $100, your markup is 25% because you added $20 on top of the $80 cost.

What Is Margin?

Margin (also called gross profit margin) is the percentage of the selling price that is profit. It's calculated as a percentage of the selling price, not the cost.

Margin % = (Selling Price − Cost) ÷ Selling Price × 100

Using the same example — a product that costs $80 and sells for $100 — your margin is 20% because $20 is 20% of the $100 selling price.

Markup vs. Margin: Side by Side

The same $20 profit produces different percentages depending on which metric you use:

Markup: 25% (profit ÷ cost)
Margin: 20% (profit ÷ selling price)

This is why a 25% markup does NOT equal a 25% margin. The higher the percentage, the wider the gap between the two.

Common Conversion Table

5% margin = 5.3% markup
10% margin = 11.1% markup
20% margin = 25% markup
25% margin = 33.3% markup
33% margin = 50% markup
40% margin = 66.7% markup
50% margin = 100% markup

Why the Confusion Costs You Money

If you aim for a 25% margin but tell your team to apply a 25% markup, you'll actually get a 20% margin — losing 5% profit on every sale. On $100,000 in annual sales, that's $5,000 in lost profit. The higher your volume, the more costly this mistake becomes. Use our markup and margin calculator to get the numbers right every time.

When to Use Each Metric

Use markup when setting prices from cost — common in retail, manufacturing, and wholesale businesses where you know your unit cost.
Use margin when analyzing profitability — used in financial statements, investor reporting, and comparing business performance across industries.

Most businesses track both. Markup helps with day-to-day pricing decisions, while margin tells you whether your business is actually profitable.
